I just limited my four month old daughters pacifier time. Now she has started using her thumb. What should I do ?

Trust me, thumb is worst than pacifier. I know of a 15yo who still can't quit thumb sucking habit. Pacifier is easier to quit.

Amputate. No, I'm just kidding. I think pacifier is still the lesser of two evils. Failing which, I would suggest mittens.

Use mitten and give pacifier. pacifier is easier to wean off than thumb.

thanks

i use soothies instead of pacifier

try give her a teether
